I then tried two analyses of tartar emetic, which I give here. 
In the first a globule of sulphur remained, and I had to drive 
it off at last by heat, giving of course considerable loss. In 
the other the sulphur was completely oxidized.

Ir has been stated by Houzeau,* that alcohol exposed to the 
action of ozone is instantl oxidized, with the formation of 
aldehyde, acetic ae and hydrogen peroxide, and that ether, 
under similar onditions, undergoes an analogous changé, 
being even cine aoe. oxidized, with the production of 
hydrogen peroxide. oes not appear, however, that either 
the conditions of sia! ason of ozone on these substances, oF 
the nature of the compounds formed, have been much further 
studi ith a view to determine some of these points, and 
especially to ascertain whether ozone could be advantageously 
used in the production of acetic acid from alcohol, an eX
